Binary 133 = 100001012
The binary for 133 is 10000101

As any other integer, 133 can be written as sum of potencies to the power of 2, known as binary code. Here’s the proof that 10000101 is the binary of 133:

1×2^7 + 0x2^6 + 0x2^5 + 0x2^4 + 0x2^3 + 1×2^2 + 0x2^1 + 1×2^0 = 133

## Convert 133 to Binary

Now you already know the most important thing about 133 in binary form. 10000101 is binary 133. That is if the binary in unsigned.

If 133 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00010000101 in which the leftmost bit is the sign bit, followed perhaps by more trailing 0’s, and then by magnitude bits.

The reason to have the binary 133 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 133 signed using two’s complement, will start with one or more 1’s, but the exact code for -133 decimal to binary depends on the signed number representation system and number of bits available.
